Dear Sir
I guess you understand the difference between pinga and cachaça... you can use both to have the best caipirinhas.
Also, I can add caipirinhas are made directly into the serving glass... not trasferred from one glass to other iced glass. Popular places they do caipirinha that way.
Using other more refined methods (as pouring muddled fruit to other glass) you can see at refined places, only.
Great site, congratularions
